(5-bromo-2-fluoro-4-methoxyphenyl)methanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: PBr3 (4.7 g, 17.4 mmol) was added drop-wise to a solution of (5-bromo-2-fluoro-4-methoxyphenyl)methanol (4.1 g, 17.4 mmol) in anhydrous CH2Cl2 (40 mL) at 0° C. The mixture was stirred at room temperature for 3 h and poured into ice water. The pH was adjusted to 8 with saturated aqueous NaHCO3. Extractive work up with CH2Cl2 gave the title compound (4.9 g, 94.8%) as a white solid which was carried on without purification. 1H NMR (DMSO-d6, 400 MHz) δ 7.56 (d, J=8.0 Hz, 1H), 6.65 (d, J=11.6 Hz, 1H), 4.46 (s, 2H), 3.89 (s, 3H).

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
